I get soooo frustrated when watching a movie and suddenly the movie freezes or stutters. My friend told me about how Brasso can fix dvd scratches so I tried it... and it worked! Maybe you'd like to try it out for yourself so here are the directions...
First of all... you can buy it at Walmart. At least that's where I found it. Also, be aware that it is highly toxic so don't let your kids around it, and you might want to wear gloves (although I didn't).
1. Use a small amount on a soft cloth and go over the area that is scratched from the inside of the dvd to the outer edge in a straight stroke.
2. Do this until it is rubbed in and shiny.
3. Run the dvd under hot water to rinse off any residue.
4. Dry with another soft cloth.
*my friend said you can also do this with a regular paste toothpaste (nothing added and it cannot be a gel or whitener)--just good old fashioned paste, but I haven't tried this method out, so you're on your own.
